IMPROVEMENT IN DUMPING-CARS.

The Schedule referred to in these Letters Patent and making part of thesame'.

To all whom it may concern.-

Be it known that I, Tnnononn BOOTSMANN, of 'Tompkinsville, in the countyof Richmond and State of New York, have invented a new and usefulImprovement in Dumping-Car's; and I do hereby declare the following tobe a full, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same, reference being -had to theaccompanying drawing forming part of this specification, in whichdrawing Figure 1 represents a side view of this invention.

Figure 2 is a transvcrsesectiou of the same.

Similar letters indicate corresponding parts.

This invention relates to a dumping-car, which is intended particularlyfor portable railroads, and which is so arranged that it can be easilyloaded, that the operation of dumping is facilitated, and that it is notliable to rnnofi the track.

The improvement consists in the arrangement of revolving stops, incombination with an arm attached to the bottom of the hinged box, eachof said stops being provided with a notch or opening, in such a mannerthat, when the solid parts of both stops are opposite the arm,-the boxis retained in an upright position, and when the opening of either ofthe stops isbronght opposite the arm, the box can be tipped over and itscontents dumped. the stops being always in such a condition that theycan be operated with little trouble or expenditure of power.

\Vith the trucks of this oarare combined two sets of satiety-rollers,one set being applied on each truck, and said rollers act either on asafety rail, placed between the main rails or on the mainrailsthemselves, in such a manner that the car, when running down a steepgrade, or during the operation of dumping, is prevented from running 0dthe track or from tipping over.

In the drawing- The letterA designates the box of my dumpingcar, whichis made in the form of the segment of a cylinder, as shown in thedrawing,'so that it can be conveniently loaded, and. its contents can bereadily dumped toward either side.

To the bottom of this box are secured two brackets, '11,- which areconnected by pivots, b, to standards, a, rising from a beam or reach, B,that forms the con nection between the two trucks, 0.

To the reach B are secured the revolving stops, d, one to each of itssides, and these stops straddle an arm, 0, which is fastened to thebottom of the box A, (best seen in fig. 2.)

Each of the stops is provided with an opening or notch, f, and if one ofthe stops is brought in sucha position that its opening is opposite thearm e, the box A can be tipped over toward the side opposite to saidstop, but if both stops are brought in such a position that their solidparts are opposite the arm 6, the box A is retained in an uprightposition.

Each of the stops (2 connects, by a rod, g, with a bell-crank lever, h,which is pivoted to the reach B, near one of its ends, so that, bypressing on the long arm of one of said bell-crank levers, theappropriate stop can be revolved-and its opening brought opposite thearm 0.

From this description it will be readily seen that, even if the load ofthe box should not be uniformly balanced, the pressure of the arm 6against either of the stops (1 cannot be of great consequence, and, inall cases, but little power will be required to turn the desired stopfor the purpose of dumping the contents of the box.

With each of bell-crank levers It may be connected a spring, for thepurpose of returning the same, together with their stops, to theirlocking position, and,

in this case, the openings of the stops are providedwith flaring lips,i, to allow the arm 0 to force the stops back against the action of saidsprings, when. the box is raised up after its contents have been dumped.

' The trucks 0 may be conuectcdto the reach B by means of king-bolts,and, in this case, the box A is steadied by roller-arms, j, secured tothe standards a, and bearing on a segmental track attached to thesurface of the trucks, (not shown,) or, instead of this, the reach maybe firmly connected to the trucks, and the axles k, may be mounted inswivel-boxes, Z, so as to allow the wheels, in, to accommodatethemselves to curves in the track. 7

From the axles. It are suspended arms, 11, which form the bearings forsafety rollers 0, working in a T- shaped rail, 1), placed between themain rails, q, or

said safety-rollers may be so arranged that. they work in the main railsthemselves.

By the actionof the safety-rollers, the car is prevented from runningoff the track in turning curves, or in going down steep grades, anditis'also prevented from tipping over bodily when the box A is allowedto drop suddenly toward one side or toward the other.

What I claim as new, and desire to secure by Letters Patent, is-- l. Therevolving stops cl, in combination with an arm extending from the hingedbox ota'dumping-car, substantially as described and for the purposes setforth.

2. The safety-rollers, hinged to. the trucks of a dumping-car, andserving to retain the car, iu cor nbination with a center rail, p, onthe track, particularly during the act of dumping, substantially as setforth.

This specification signed by me this 10th day of May, 1870. p

T. BOOTSMANN.
